A Richmond Hill man was driving in his neighbourhood Saturday night when he spotted a bank bag full of cancelled cheques on the side of the road.

He took the bag to a police station after a quick peek inside revealed the personal information of hundreds of bank customers.

Mair Afdasta told police he was in the Bayview Avenue and Major Mackenzie Drive area when he spotted the redbag at the side of the road with the HSBC bank logo emblazoned at the front.

When he got home, Afdasta did a Google search on the bank number and discovered the bag belonged to the HSBC branch at Bayview and Major Mackenzie.

"There were about 300 of them," he told CTV Toronto Saturday night. "There were more documents in there destroyed by the rain."

Afdasta said he tried to contact the bank but didn't have much luck.

York Regional Police are speaking with bank officials as they investigate how the sensitive information ended up on the side of a road.
